fg y@ nrlllliv )juffen/Yo?)- Patented Nov. 2.4, 14931 JOHN O. PURDIE, F CHICAGO, ILLINOIS THERAPEUTIC DEVICE Application led September 16,1926. Serial No. 135,712.

My invention relates to therapeutic devices and has for its object the provision of a new and improved form and arrangement of parts in a device of this type for administering treatmentsby theuse of oxygen together with water or some other liquid and preferably with the oxygen and water heated. 'It is the object of my invention to provide an improved form of means for delivering a stream IO of oxygen and a suitable liquid upon the surface of a part being treated, and to provide such means in a form adapted for carrying off the liquid and the oxygen so as to avoid so far as Vpossible any inconvenience to the patient and to avoid anyexcessive amounts of oxygen in the air of the room where the treatments are being given.

It is another object of my invention to im prove devices of this type in vsundry details 250 hereinafter pointed out. The preferred means by which I have accomplished my sev` eral objects are illustrated in the drawing and are hereinafter specifically described. What I desire to' cover by Letters Patent is set forth in the claims.

Y The drawing is a central vertical section through my improved device, certain of the `parts being broken away for clearness of illustration.`

Referring to the drawing,-.-10 indicates a receptacle preferably in the form of a metal cylinder open at its upper end and provided with screw threads for .receiving a closure head 11 also preferably of metal. The head '35 .11 is provided with a transversely extending duct 12 into the end of which extends a nipple 13 upon which is mounted a rubber'tube 14E through which oxygen is adapted to be fed under pressure from any suitable source. lo Leading from the end portion of the duct 12, I have provided a piece of metal tubing 15 which extends downwardly from the head 11 for some little distance and is then turned backwardly upon itself for passage through another opening in the head 11 into vcommunication with a chamber 16'in the head, such chamber 16 being provided by the use of a plug 17 inthe duct 12. The return por- .,750 tion of the tube 15 is bent in the form of ai tained in the receptacle.

lmounted upon the lower end of the sleeve 19,

the heating element 2O being electrically con- ,5 nected within the sleeve 21 with the wires of an yelectric cable 22 leading from any suitable ,source of electrical energy, the arrangement being such that the sleeve 21 with the heat ing.' element 2() can be withdrawn from the n, sleeve 19 when desired. Y

The head 11 is provided further with pieces of tubing 23 and 24 opening into the upper end of the receptacle 10 at about the center of the uper end of the receptacle. The tube 23 communicates with the chamber' 16 `above described, while the tube 24 communicates with a chamber 25 separated from the chamber 1G by a partition Vithin the chamber 25, there is mounted an ejector device 27 .30 terminating in a nozzle 28 extending some little distance beyond the head 11. 'A tube vided at its lower end portion with a weight gg ydevice 32 which is provided for causing the rtube to seek the lowest part of the receptacle l() Vwhen the receptacle is placed in position `on its side so as to keep the open end of the tube always in contact with the water con- A very light coiled spring 33 is mounted upon the tube -31 for preventing the tube from becoming kinked.

At one side, the head 11 is provided with `a-screw threaded nipple 34.- by which I relos movably mount in position a cup-shaped shield preferably formed of glass, such shield extending some little distance beyond the end of the nozzle 28 which is in centered position Yith respect to the shield 35. At its lower portion, in the position shown in the drawing, the shield 35 is provided with a nipple 36 secured in the wall of the shield and having mounted thereon a flexible tube of any desired length, such tube 37 being connected at its other end with a receptacle 33, the arrangement being such that the gas and water delivered to the shield 35 through the nipple Q3 as hereinafter described are adapted to escape through the tube 37 to tue receptacle A plug 39 is secured by means of screw threads in the upper end of the receptacle 33 for the purpose of emptying the receptacle. A flexible tube 40 is connected with the upper end of the receptacle 33 for carrying olf the oxygen from the receptacle, the tube Ll leading preferably out of the room where the device is being used.

in use, the receptacle is preferably filled with water of the desired temperature. The ond of the shield 35 is then placed by the operator in Contact with the surface of the bot y of a patient for a treatment and oxygen is admitted through the tube 14 in controlled amounts and under controlled pressures as may be desired. rlhe oxygen passes downwardly through the tube 15 and upwardly through the coil 18, the oxygen in the passage through this tube being brought to substantially the same temperature as that of the water in the receptacle 10. The oxygen passes then from the chamber 16 to the body of the receptacle, and thence through the tube Q-l and chamber to the ejector 27 ad through the nozzle 28. The oxygen passing through the ejector 27 causes a stream of the water to pass upwardly through the tube 31 and out through the nozzle 28 in the form Of a spray with the oxygen, the water and the oxygen being delivered upon the surface being treated. As above explained, the water and oxygen after being forced into contact with the part bein(T treated are caused to escape through the tune 37 to the receptacle 3S, the oxygen passing out through the tube l0. By reason of having the tube 37 connected with the shield at its lowermost point and at a point below the lowermost part of the front opening of the cup, the water is caused to run ofl without delay and is thus prevented from standing in contact with any part of the surface being treated. It thus is prevented from interfering with the treatment.

By making the tube 31 flexible so as to remain in contact with the water in the lowermost portion of the receptacle as the receptacle is shifted from one position to another, the device is suitable for use in a great variety of positions to meet the convenience of the operator.

If it is desired that the water in the receptacle 10 be maintained at a steady heat, or if for any other reason it is desirable, electrical energy is to be fed to the heating unit 2O through the cable 22. The heat generated by the unit 2O serves to heat the water in the receptacle l() and also to heat the oxygen passing through the coil 18.

lVhile l prefer to employ the construction substantially as shown in my drawing and as above described, l do not wish to limit my invention to the form shown except so far as certain of the claims are specifically so limited, inasmuch as it is evident that changes might well be made in the form of the device without departing from my invention.
